Dianthus plant named &#39;WP08 IAN04&#39;

ABSTRACT

A new cultivar of  Dianthus  plant named ‘WP08 IAN04’ that is characterized by pronounced compact habit, grey-green foliage, and flowers that are double and whose petal grounds are bright cherry red with a pale pink margin, and which bloom from April through October. In combination these traits set ‘WP08 IAN04’ apart from all other existing varieties of  Dianthus  known to the inventor.

Genus

Species

×hybrida

Denomination

‘WP08 IAN04’

BACKGROUND OF THE INVENTION

This application claims the benefit of priority under 35 U.S.C. 119(f) of the application for a grant of European Community Plant Breeders Rights which was filed for the instant plant variety on Jun. 30, 2008, Application Number 2008/1511.

The present invention relates to a new and distinct cultivar of hardy garden pink or carnation which is grown for use as a flowering plant for pots and containers and for planting in the garden or landscape. The new cultivar is known botanically as Dianthus×hybrida and will be referred to hereinafter by the cultivar name ‘WP08 IAN04’.

‘WP08 IAN04’ is a complex hybrid plant that is the product of a breeding program started by the inventor in 1985. The breeding program is conducted in a cultivated area of Houndspool, Dawlish, Devon, United Kingdom. The inventor selected ‘WP08 IAN04’ in 2004 for its flowers that are double and whose petal grounds are bright cherry red with a pale pink margin, and which bloom from April through October.

‘WP08 IAN04’ resulted from the controlled pollination between two unreleased and unpatented varieties, namely Dianthus code number FLA 02.28 as female parent plant and Dianthus code number 99.17 as male parent plant.

‘WP08 IAN04’ is distinguishable from the female parent as follows: The female parent is smaller in height with light pink flowers.

‘WP08 IAN04’ is distinguishable from the male parent as follows: The male parent is taller in height and has large single flower whose color is carmine with white border. In addition, the buds of ‘WP08 IAN04’ exhibit a chocolate brown coloration.

The variety of Dianthus which is considered by the inventor to most closely resemble ‘WP08 IAN04’ is the inventor's variety Dianthus ‘Coral Reef’ (U.S. Plant Pat. No. 19,660). ‘WP08 IAN04’ is distinguishable from this variety as follows: ‘Coral Reef’ bears lighter salmon-pink flowers with a pale pink edge.

Asexual reproduction of the new cultivar was first accomplished by the inventor in 2000 in a cultivated area of Houndspool, United Kingdom. The method of asexual propagation used was vegetative cuttings. Since that time the characteristics of the new cultivar have been determined stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Dianthus cultivar ‘WP08 IAN04’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘WP08 IAN04’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, however, without any variance in genotype.

-   -   1. Dianthus ‘WP08 IAN04’ exhibits a compact habit.     -   2. Dianthus ‘WP08 IAN04’ blooms profusely from April until         October.     -   3. Dianthus ‘WP08 IAN04’ exhibits double flowers that are bright         cherry red with a pale pink edge.     -   4. Dianthus ‘WP08 IAN04’ exhibits grey-green foliage.     -   5. After nine months of growth, the height of the foliage mound         of Dianthus ‘WP08 IAN04’ is 30 cm to 35 cm; the width is 14 cm         to 16 cm.     -   6. Dianthus ‘WP08 IAN04’ is perennial and is hardy to −15° C.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Dianthus variety ‘WP08 IAN04’ showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘WP08 IAN04’.

The drawing labeled as FIG. 1 depicts an entire flowering plant.

The drawing labeled as FIG. 2 depicts a close-up view of the flower.

All drawings were made of 9 months old plants which have been grown in 1.5-litre containers in a cold glasshouse in Devon, United Kingdom. No chemicals were used to treat the plants. All drawings were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar ‘WP08 IAN04’. Data was collected in spring from 1.5-litre container plants in spring, and grown indoors in Devon, United Kingdom. The color determinations are in accordance with the 2007 edition of The Royal Horticultural Society Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. The colors of stems, leaves, calyx, and epicalyx have been noted on plants which retain the characteristic waxy bloom of Dianthus. No chemicals were used to treat the plants. Growing conditions are typical to other Dianthus.
